Processing Thermoplastic Composites in a Press and by Tape Laying—Experimental Results

Abstract

Tests were conducted to validate the thermoplastic manufacturing process models described by Mantell and Springer. In the tests, APC-2 graphite/PEEK plates were fabricated both in a press and with a specially constructed tape laying apparatus. The tem perature, intimate contact and bonding inside the plates were measured. The data agreed well with the results of the model.

Weld Strength Assessment for Tape Placement

“…The short beam shear test, according to the ASTM-D2344 standard, is most widely used to quantify the weld strength, e.g. [10][11][12]. The test requires relatively thick specimens which makes preparation quite laborious.…”

“…The test requires relatively thick specimens which makes preparation quite laborious. As an alternative, Mantell et al [12] performed lap shear tests. The complex failure modes and stress concentration effects, however, make it difficult to interpret the results of these tests.…”

Computational and experimental analysis of fusion bonding in thermoplastic composites: Influence of process parameters

“…The adhesion of the bonding was evaluated using the most common test method: the lap-shear test (Mantell et al, 1992b). The tests were performed on a Zwick testing machine mounted with a 10 kN-force cell.…”

A Heat Transfer Analysis of the Fiber Placement Composite Manufacturing Process

“…A number of heat transfer models have been proposed for investigating the thermal history of fiber placement [1][2][3][4][5][6][7][8][9][10] and filament winding [11][12][13][14][15][16]. The techniques used are classified into two categories.…”

“…The techniques used are classified into two categories. In the first one, a quasi-steady state is assumed to prevail throughout the process, and the steady-state heat transfer problem in the Eulerian framework [1][2][3][4][5][9][10][11][12][13] is analyzed; and the transient heat conduction equation in the Lagrangian framework [6][7][8][14][15][16] is solved in the second.…”
