Abstract : Nine laminates of various thicknesses, fabricated from CTL-91LD phenolic resin and reinforced with 181-A1100 glass fabric, were evaluated in tension, compression, and flexure. The laminates covered the thickness range of 0.017 to 1.453 inches. Results indicate that strength in tension, elevated-temperature compression, and flexure reached a maximum or nearly maximum value for laminates at about 1/8-in. thickness; below 1.8 in., strength decreases gradually at first, and then abruptly with decreases in laminate thickness. A slight increase in tensile strength for thicknesses above 1.8 in. was noted, but decreases were found in the other tests. The normal compressive strength value was shown to be at a maximum between thicknesses of about 1/4 and 1/2 in. with
