“…Adhesion failure is the failure mode that occurs when minimal adhesive is present on one or both sides of the surface bonding. It is characterized by the absence of adhesion on one of the surfaces due to the hydration of the chemical bond formed [15]. This can occur when the adhesive dries before a bond with the adhesive is created.…”

Composite materials have been widely used in various industries due to their high specific strength and stiffness. Although composite materials have the flexibility to create designs with good integrity, connections between structures may have to be made due to the design of the structure and the cost of the manufacturing process. This paper will evaluate especially the shear strength of composite joints using the single-lap joint method with various adhesive types and ply stacking orientation face of the joint. The composite was made using a vacuum-assisted resin infusion manufacturing technique using carbon fiber and chempoxy resin with specific unidirectional, orthotropic, and quasi-isotropic arrangement orientations. The results showed that the using of the same adhesive as the composite resin type, chempoxy adhesive had the highest value a lap shear strength of 11,43 MPa compared to other adhesives with tested interface layer 0°. The variation of the direction interface layer is a variable that has a significant effect on lap shear strength. The results showed that the quasi-isotropic with interface layers 0°, 90°, and +45 ° has lap shear strength of 7.42 MPa, 6.34 MPa, and 5.46 MPa respectively. The difference in shear strength values in lap joints with variations direction of stacking ply in the interface layer of the adhesive is also evident from the failure modes that occur in the specimens.

“…What is more, the adhesive materials show relatively low durability. These materials are very sensitive to repair's conditions, as well as, they have got limited shear and long-term strength; that is, an ability to transfer constant loads in time, and limited fatigue life -an ability to transfer changing loads [26][27][28][29][30][31]. Without familiarity with these properties, the application of adhesive materials in repairs is burdened with the risk of damage of a repaired element in a relatively short time after the performed repair.…”

The paper presents research proposition of methodology of adhesive composites' properties assessment, which was developed on the basis of numerous own researches and analysis of references. Using the proposed methodology, there were conducted experimental tests of a new Belzona 1831 adhesive composite, which can be applied on the wet and insufficiently cleaned surfaces. It appeared that the tested material exhibits much lower compression strength and creep resistance in connection to field repairs of military equipment, than previously tested adhesive composite of "super metal" group -Belzona 1111. Therefore, it does not seem to be useful with repair that guarantee long lasting effectiveness, but only temporary repairs with relative low level of load of repaired element. In contrast to Belzona 1111, the researched adhesive composite can be applied on the wet surfaces since it showed adhesion to steel wet surfaces. Keywords: durability of materials, adhesive composites, mechanical properties of adhesive composites.METODYKA OCENY W£AOECIWOOECI KOMPOZYTÓW KLEJOWYCH Streszczenie -W pracy przedstawiono autorsk¹ propozycjê metodyki postêpowania badawczego, maj¹cego na celu okreoelanie w³aoeciwooeci kompozytów klejowych, istotnych ze wzglêdu na naprawy polowe sprzêtu wojskowego, z uwzglêdnieniem ich doraŸnooeci oraz trudnych warunków realizacji. Na pierwszym etapie postêpowania badawczego okreoela siê w³aoeciwooeci mechaniczne wykorzystuj¹c próbkê cylindryczn¹ wykonan¹ z badanego kompozytu (rys. 1), na drugim zaoe w³aoeciwooeci wytrzyma³ooeciowe próbek wa³eczkowych obci¹¿onych na odrywanie (rys. 2). Na trzecim, fakultatywnym etapie jest przewidziana ocena w³aoeciwooeci wytrzyma³ooeciowych badanego tworzywa, w odniesieniu do ró¿nych specyficznych czynników, takich jak: rodzaj klejonego materia³u, sposób przygotowania powierzchni lub temperatura utwardzania z³¹cza klejowego. To badanie proponuje siê realizowaae z wykorzystaniem próbek p³askich, obci¹¿onych na oecinanie (rys. 3). Na podstawie zaproponowanej metodyki zbadano w³aoeciwooeci nowego materia³u Belzona 1831 oraz porównano je z cechami znanego i przebadanego wczeoeniej kompozytu klejowego Belzona 1111. Wykazano, ¿e zaproponowana metodyka oceny w³aoeciwooeci kompozytów klejowych wydaje siê u¿yteczna dla potrzeb okreoelenia ich przydatnooeci do napraw polowych sprzêtu wojskowego. S³owa kluczowe: wytrzyma³ooeae materia³ów, kompozyty klejowe, w³aoeciwooeci mechaniczne kompozytów klejowych.
